摘要
某煤矿含有大量的油页岩 ,属煤系高岭岩系列。根据油页岩的鉴定结果和实验室初步试验研究 ,认为可以利用该油页岩干馏脱水后生成的偏高岭石 ,作为生产高强混凝土的添加剂 ;也可以经过脱除显色物质后 ,制取高附加值的优质高岭土产品或深加工生产高质量的白炭黑及铝盐等产品。综合利用油页岩资源 ,是该煤矿可持续发展必须解决的重要问题。
There is a great deal of oil shale, belonging to coal series Kaolin, in a coal mine. In this study,it is considered that the metakaolin produced by dry distillation and dewatering of oil shale may be used, as an additive, to produce high-strength concrete. Yet, the oil shale in which the colourated substances are removed may be used to produce the fine Kaolin or high-quality activated silicon dioxide as well as aluminum salt products through deep processing. The comprehensive utilization of oil shale resource is main problem necessary to be solved for sustainable development of this coal mine
